Application filed June 16,

' "This 'inventionappertains to new and usevention, V portion of of reference ful improvements in flue opening stoppers and has particular reference to such a stopper designed primarily for closing the stove pipe opening in a chimney after the stove pipe has beenrremoved therefrom.

An important object of the present invention is to provide an improved flue opening stopper of the above character which will be durable and eflicient in use, one which will be simple and easy to manufacture and one which can be placed upon the market at a small cost.

Another object of the present invention is to provide such an improved flue opening stopper of the above character embody ing a cylinder or thimble having inner and outer disks separated so as to provide an airspace therebetween. 1

Another object of the present invention is the provision of such an improved flue opening stopper ofythe above character including a cylinder or thimble adapted to be inserted within the flue opening and hav in a stationary outer or cover disk and an inner disk disposed within the cylinder and spaced from the cover disk to provide an air space therebetweem'said inner disk serving to prevent the heat from reaching the cover disk,

Numerous" other objects and advantages of the present invention will become more readily apparent during the coui'se of the following description when taken in. connection with the accompanying drawings. 7

In the drawings forming a part of this application and wherein like characters denote corresponding parts throughout the several views:

Figure 1 is a front view'of a portion of a chimney showing a flue opening stopper associated therewith and constructed in accordance with thepresent invention. 7 Figure 2 is a side elevation of the improved flue opening stopper showing the same in position within the flue opening.

Figure 3 is a vertical sectional view taken on line 33 of Figure 1.

Referring now' more particularly to the accompanying purpose of illustration has been disclosed a preferred the letter A generally indicatesa a conventional: chimney having the usual flue opening 10 and B the present drawings wherein for the" embodiment of the present in-.'

improved stopper 'foi' 'closing the said flue opening after the stove pipe has beenremoved therefrom.

'T'he stop-per B :em' bodies in its construe tion a' cylinder ortlri mb'le 1'1 which "is adapted to be inserted within the flue opening after the stove pipe has been removed therefrom, said cylinder being formed of a single length of material, the adjacent ends of which are secured togetherin any suitable manner such as bymeans' of rivets or other fastening elements 12. i i

The outer end. of thecylinder 11' is provided with the outwardly directed annular flange 13 and received over this flange is the inturned annular flange 14 formed on the outer or cover disk 15 which serves" to' close the outer end of the said cylinder. 7 i

The outer surface of the cylinder or thimble .11 is formed intermediate its ends with the circumferential groove 16, the provision of which results in the formation'of a corresponding circumferential rib 17 ".011 the inner surface of the said cylinder. I

Received within the cylinder 11 and con: tacting with the circumferential rib 17 is a second or inner disk 18 provided with the annular peripheral flange 19 contacting with the inner surface ofthe cylinder 11. It will thus be seen that the circumferential rib 17 serves toretain the inner disk in spaced relation to the outer'or'cover disk so as ,to provide an air space therebe tween. The inner disk 18 acts to prevent the heat within the chimney from reaching the cover disk '15 so that the provision of the air space between the outer and inner disks is an element of great safety. I

The inner end of the cylinder 11 may be formed with dia l disposed comga' tions as indicated at 2 0 and as the cylinder is being inserted withinthe flue openinglO, these corrugations serve to scrape the wall thereof so as'to remove therefrom any soot, dirt or the like which may have become also'a'cts to clean the wall of the flue open- 7 ing as itis placed in position. Theinner disk 18 may be firmly secured, within the cylinderll oruinay be removably positioned therein as desired. Also, the inner portion" of the cylinder 11' can be filled with cement or the like, if desired, thereby adding still greater safetyto the stopper.

From the foregoing, it is b-elieved that 1 00 attached thereto. Thus, the present device a the construction and use of the present invention will be readily appreciated and it is to be understood that changes in the details of construction may be resorted to Without departing from or sacrificing the spirit of the invention so long as such changes fall within the scope of the appended claims.

\Vhat is claimed is: v 1. In a stopper of the class described, a cylinder having an annular flange at its outer end, a cover disc having an inturned 15 rugations formed 1 in said cylinder at the at its outer end and diagonally disposed cor-.

rugations at its inner end, a cover disk having an inturned peripheral flange engaging over the flange of the cylinder, and a second disk positioned Within the cylinder and held spaced from the cover disk by means of the said rib.

In testimony whereof I affix my sigma- WINFIELD soUTHAnD;
